Automatic stamping device

The invention discloses an automatic stamping device. In stamping, a material band is compacted and positioned by a positioning mechanism, an upper die is driven by a first driving mechanism to move downwards to be matched with a lower die for stamping; after the stamping is completed, the upper die is lifted, and a material guide table is driven by a second driving mechanism to move upwards so as to make an insertion pin on a material pulling seat inserted into through holes at two side edge parts of the material band in a feed chute; the material pulling seat is driven by a third driving mechanism to move to the right so as to pull the material band to move to the right; and after a preset stroke is achieved, the material guide table is driven by the second driving mechanism to move downwards so as to make the insertion pin separated from the through holes at the two side edge parts of the material band, and the material pulling seat is driven by the third driving mechanism to move to the left to return to the original position. Compared with the original manual stamping mode, the automatic stamping device has high precision and high production efficiency, the production efficiency is greatly improved, manpower is greatly saved, and simultaneously the labor intensity is reduced.
